性质描述: 白色结晶。熔点73-74℃,沸点274℃,138℃(1.33kPa)。微溶于水、甲醇、乙醇,溶于乙醚和二硫化碳,易溶于苯和氯仿。能升华和进行水蒸气蒸馏。
生产方法: 1.由2-萘酚与甲醇反应而得。将2-萘酚、甲醇和硫酸在85-90℃加热回流6h,冷却,过滤,洗涤至中性。减压蒸馏,收集168-180℃(2.67kPa)馏分,经甲醇重结晶得成品,收率约70%。2.由2-萘酚与硫酸二甲酯反应而得。在反应锅内投入水、氢氧化钠溶液和2-萘酚,在10℃加入硫酸二甲酯,控制料液温度不超过36℃。搅拌反应3h,然后加热至76-80℃反应1.5h。冷却至50℃左右加入氨水至pH值为11,冷却,结晶,过滤得粗品。用乙醇重结晶得2-甲氧基萘精品。2-甲氧基萘也可用升华法提纯,而它的类似产品2-乙氧基萘(橙花素)加热时不会升华,一般用减压蒸馏的方法精制。
用途: 该品是一种香料,具有橙花香气,用作皂用香精及廉价的化妆香精。2-甲氧基萘是有机合成中间体,用乙酐在三氯化铝存在下乙酰化可得到6-甲氧基-2-萘乙酮。将硝基苯及2-甲氧基萘投入反应锅中,在5℃慢慢投入三氯化铝(温度水超过15℃)搅拌1h后降温至5℃,慢慢加入乙酐,然后逐渐升温,在70-80℃反应近2h,冷至30℃以下,加入1:1盐酸溶液,搅拌后分去水层。用水洗涤油层,除去无机盐,再用水蒸气蒸馏除去硝基苯,以石油醚提取,将提取液浓缩、冷却、结晶、过滤,得6-甲氧基-2-萘乙酮,收率为50%。这是一种医药中间体,用于生产消炎镇痛药萘普生。2-甲氧基萘也用于三烯高诺酮和计划生育药物18-甲基炔诺酮的生产。
